THE

PAN-COVER.

SPECIFICATION forming part of Letters Patent No. 487,443, dated December 6, 1892.

Application filed July 13,1892.

To all whom it may concern;

Be it known that I, HERMAN HOLLANDT, a citizen of the United States, and a resident of Jersey Oity,in the State of New Jersey, have invented a new and useful Improvement in Pan-Covers, of which the following is a specification.

This invention relates to sheet-metal covers for use in connection with ordinary rectangular dripping'pans to form self-basting roast The invention consists in a novel domeshaped cover of sheet metal, having peculiarlyformed seams, rims, and corners, with or without a sliding regulator or valve, the same being adapted to be manufactured without the aid of swaging-dies or seaming-rolls, as hereinafter set forth and claimed.

Theobjects of the invention are to render the pan-cover of attractive appearance, light, and sufficiently strong and to dispense with skilled labor and expensive machinery, as far as possible, in its production.

Three sheets of drawings accompany this specification as .part thereof.

Figure 1 of the drawings is an end elevation of a covered pan, illustrating my said invention. Fig. 2 is atop View projected from Fig. 1. Fig. 3 represents a vertical cross-section through the cover and pan at mid-length. Fig. 4: is a bottom view of the cover. Figs. 5 and 6 are small-scale plans of the main blank or flat iron and the cover-body or main portion of the cover as bent up therefrom; and Figs. 7 to 20, inclusive, are detail views on a larger scale, illustrating the processes by which the cover is completed, Fig. 7being a plan of an inside seam-strip blank, flat; Fig. 8, a like view of an outside seam-strip or rib blank, flat; Fig. 9, a perspective view of one of the latter shaped; Fig. 10, a horizontal section through a finished seam; Fig.v 11, a perspective view of adjoining ends of two rim-pieces; Fig. 12, a plan view of a corher-piece blank, flat; Fig. 13, a top view of the samefurnished with its preliminary bends; Figs. 14 and 15, top and bottom views of a corner with one rim-piece in position; Figs. 16 and 17, top and bottom views of the same with the adjoining rim-piece in position; Figs.

18 and 19, top and bottom views of thesame,

Serial No.439,888. (No model.)

showing the corner-pieces fastened together; and Fig. 20 a bottom View of the completed corner.

Like reference-letters indicate corresponding parts in the several figures.

The improved pan-cover as an article of commerce and of use is represented at A on Sheet 1 of the drawings. It comprises an oblong dome-shaped body in one part, having convex-curved ends a and sides I), the seams between which are closed and masked by external hollow ribs 0 and internal seam-strips d, united at their upper ends by rivets w and interlocked at their lower ends by clips 0 projecting from said ribs 0. Outwardly and downwardly projecting rims e f and cornerpieces g complete the cover at its bottom, rendering it free from cutting-edges and angles. It is preferably further provided with rigidlyattached handles 77. and with a regulator or valve i, sliding in a frame j, which is riveted to one of said ends a around a corresponding hole It in the body-iron. These attachments h '5 j are not, however, essential to the present invention and need not be of peculiar construotion.

A suitable sheet-iron pan B, having folding handles 7L beneath rigid handles it on the pan-cover, is represented in Figs. 1 and 3, and a suitable internal frame or grid to complete a self-basting roaster is shown in crosssection at'O in Fig. 3 by way of illustration; but said pan and grid form no part of this invention.

The process of making the body of said pan-coverA and closingand maskingits seams, as aforesaid, is illustrated on Sheet 2 of the drawings, being as follows: A rectangular sheet of iron of proper weight and dimensions is provided by punching with curvilinear corner-notches z, Fig. 5,,and with the said hole is and rivet-holes at its corners if the body of the cover A, as represented by Fig. 6, by bending down the several leaves a I) over a suitable form and rebending their outer edges to form said rirn-sections y. The fiat blanksc' (1, Figs. 7 and 8, of the ribs 0 and seam-strips d having been punched to provide them with rivet-holes 00 and the former swaged into shape, as represented by Fig. 9, the cover-body, Fig. 6, is provided with corresponding rivet-holes x to receive the rivets m and with slots s to receive the rib-clips 0 One of the seam-strip blanks d is then placed inside and one of the rib-blanks 0' outside of each seam and their rivet ac and rib-clips c are passed through the corresponding holes 00 and slots 3 and riveted and clinched, respectively. The fastening formed by the clinched rib-clips is shown in sectional detail by Fig. 10.

The modes and processes of forming the rims e f and corner-pieces g and uniting them with each other and with the body of the pancover A are illustrated by Figs. 11 to 20, inclusive, on Sheet 3 of the drawings and are as follows:

The rims e f on the respective ends and sides of the cover A are parts in common of rim-strips R R, which are formedin suitable lengths from thin sheet-iron by a bend- Each end of each rim-strip ing operation. R is provided in continuation of the bottom of the rim 6 with a tongue t, and each end of each rim-strip R" is provided wit-h a like tongue 25 and with another one i at right angles to the outer side of the downwardly-projecting rimf.

The corner-pieces g are formed from fiat blanks g, one of which is represented by Fig.

12, the dotted lines in this figure representing the lines along which the blank is bent.

Each blank is first bent so as to give its inner 1 edges g a permanent underlying position, as

in Fig. 13. One of the rim-strips-R" for ex- 1 in the example is next applied endwise to the tongue 15 and the corresponding edge portion g and simultaneously to the corresponding rim-section y, the latter and said edge 9 being embraced by the rim 6, as before, while said tongue t is embraced by the downwardlyto neatly mask them and to complete the corner, as shown in bottom view by Fig. 20. The other corners of the cover are completed in substantially the same way, and the cover is thus finished as regards the present invention.

Details of shape and proportions may be varied, and other like modifications will suggest themselves to those skilled in the art.

Having thus described the said pan-cover, I claim as my invention and desire to patent under this specification-- 1. A dome-shaped pan-cover of bent-up sheet metal, having convex-curved ends and sides, with the seams between closed and masked externally by overlying metallic ribs, substantially as hereinbefore specified.

2. A dome-shaped pan-cover of bent-up sheet metal, having convex-curved ends and.

sides, with the seams between closed and masked by external ribs and intern-a1 seamstrips which are attached at their upper ends by rivets common to both and interlocked with each other and with the cover-body at their lower ends by clinched clips projecting from said ,ribs through slots in said coverbody on both sides of each seam, substantially as hereinbefore specified.

3. A domeshaped pan-cover of bent-u p sheet metal, having convex-curved ends and sides and outwardly-projecting rim-sections and provided with outwardly-projecting hollow rims which inclose said rim-sections and downwardly-projecting hollow rims integral with said ontwardly-project-in g rims, substantially as hereinbet'ore specified.

4. A dome-shaped pan-cover of bent-up sheet metal, having convex-curved ends and sides and outwardly-projecting rim-sections forming parts of the cover-body, rim-strips embracing said rim-sections and interlocked with each other at the corners of the cover, and corner-pieces interlocked with said rim-strips at top and clinched at bottom, substantially as hereinbefore specified.

HERMAN HOLLANDT.
